OIL-BURNER.

Specification of Letters Patent.

Patented' May 19, 1914.

Application filed August 21, 1913. Serial No; 786,016.

c wherein the burner tube extends centrally of an air directing conduit, the air being admitted through an annular opening in the base which is adjacent the inner periphery of the 'said air directing conduit, and the portion of the base directly beneath the said burner tube forming a pan for the receiving of suflicient liquid fuel for the initial heating of the vaporizing tubes.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in thev details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illustrated, in which Figure 1 is a side view in elevation of my improved oilburner. Fig. 2 is a vertical cross sectional view taken through the longitudinal axis thereof. Fig. 3 is a top plan view of my `improved burner showing one of the air directing conduits in cross section. Fig. 4 is a. vertical cross sectional view taken through one of the air directing conduits.

Referring to the drawings in which simi-` tance thereabove, The base 1 is providedA with the two elevated platforms 1 -4 adjacent the ends of the same, upon which platforms are positioned they burner tubes and air directing conduits. The elevated platforms 4 4 are of the same thickness kas the remaining portions of the base but' are 'y spaced a slight distance thereabove, thereby preventing anyk foreign material from coming directly into contact with the under portions of the platforms through which the air is delivered to the burner tube. Extending through the platforms 4 1 are the annular openings. 5, the same being provided with upstanding rims 6 at the inner and outer peripheries thereof. The annular openings 5 are adapted to supply air from beneath the base 1 which when installed in a cooking range will be from the ash pit to and around the burner tubes whereby the gas will be mixed with a suitable quantity of air for the burning thereof. In order that the gas supplying pipes 7 may communicate with the upstanding burner tubes 8, the peripheral rims 6 are cut away and join at 9, and the annular openings 5 are stopped at this point. In order to further strengthen the central portion defined by the inner peripheral rims 6, webs 10 extend across the annu'- lar openings 5 and suitably strengthen the pans 11.

The air directing conduits 11 are formed with a lower cylindrical portion 12, the same adapted to rest upon the platforms 1 of the supportingbase and to encompassthe upstanding outer peripheral rims 6 of the annular openings 5. In 'order that the said Vcylindrical portion 12 may rest iiush upon the platforms 4, the same is suitably notched as at 18 so as to accommodate the gas'supply pipes 7. The upper extremity of the air outline as at 15, the same being formed integral with the lower cylindrical portion 12.

The burner tubes 8 are provided with the caps 16 secured to the top thereof and through whichcap extends a slight opening forming a suitable gas duct 17, the same being positioned slightly above the lower extremity of the frustoconical portion 15 of the air directing conduit, attention being called tothe concave'cl manner in which the upper extremities of the caps 16 are formed to thereby render the cleaning of the caps more easy and to further procure an even distribution of the gaseous fuel. .The gas Vsupplying pipes" 7 are provided' with suit directing conduit 11 is frusto-conical in 18 extendsl across the burner tube and com-V municates with a downwardly extending pipe 23, the latter communicating with the pipe Q4 which extends along the supporting base and communicates with the gas supply pipes 7.

Adjustably mounted below and secured to the vaporizing tubes 18 and 19 are the deflectors 25 which comprise the disk members 26 through which extends suitable holdmeans, in the present instance a bolt 27, by which the deflector is adjustably secured to the said vaporizing tube and may be positioned directly above the air directing conduit and burner tubes to thereby deflect the flames issuing therefrom to thereby obtain a more eflicient heating of the range within which my oil burner is positioned. The portion of the base between the platforms 4 may be filled with a suitable absorbing material (not shown) such as asbestos whereby the same may be saturated with the liquid fuel and suitably burned for the initial heating of the vaporizing tubes and various parts of the burner. The asbestos absorbing material may be omitted and the fuel burnt while in a liquid condition. The pans 11 are also adapted to contain a limited quantity of liquid fuel so that the burner tubes will also be heated during the initial burning of the liquid fuel.

From the foregoing it will be apparent that my improved oil burner may be positioned within an ordinary range and positioned upon the grate whereby the air may only enter from the ash pit to the fire box through the annular openings which extend through the base of the burner.

'By constructing the air directing conduit as described, a suitable quantity of air will be admitted therein and will be temporarily stored therein whereby the same will be heated prior to its mixing with the gas which will increase the efliciency of the apparatus. The air entering through the annular openings 5 at the sides of the burner tubes converges toward the same and a uniform mixing of the air and gas will be obtained.

Having thus fully described the invention what I claim to be new and original with me is 1. .An oil burner comprising a base with upstanding posts, said base provided with an opening extending therethrough and with a peripheral rim extending around said opening, an air directing conduit encompassing the peripheral rim and resting upon said base, a burner tube arranged concentrically of said opening and Said air directing conduit, a vaporizing tube supported by said posts and extending above said burner tube, said vaporizing tube communicating with the burner tube, and a liquid fuel supply pipey communicating with said vaporizer tu e.
